Ah yes, a waste of money eh??? I can do 144 clones at a time, and need to this time of year, can't be screwing about, need efficiancy . Still what you do works for you and that's all that matters really. It's just a question of scale in my case.
like right now I need to take clones off one of my plants because she got hurt so I need the pucks right now and don't have space for alot of pots right now, I have 4 6'' pot trays with jiffy pucks soaking in them and I have 2 tryas for clones that are done and ready to be put into the dome, I already took 8 clones in not even 5 mins
